Tell me if I take what you say incorrectly.
If Trump fails to have 1237 won Primary delegates when he gets to the convention and no one has a majority (1237) on the first ballot, then you want to convention delegates to anoint Trump the nominee without having a second or third ballot, even though he never reached the majority (majority rule required since Abe Lincoln won GOP CONTESTED CONVENTION). Is that what you want?
Lincoln had a contested convention where there were no primaries. Entirely different.
I don’t want anyone who had far fewer delegates to be anointed
